.SH "NAME"
bugle-stats_nv \- gather performance data from NVPerfSDK
.SH "SYNOPSIS"
.sp
.nf
filterset stats_nv
{
    flush "\fIyes\fR"
}
.fi
.SH "DESCRIPTION"
.PP
The
stats_nv
filter\-set extracts data from certain NVIDIA GPUs using NVPerfSDK\&. This filter\-set is only built if the appropriate header file is present at compile time, and also requires a suitably configured driver and GPU (refer to the
\m[blue]\fBNVPerfSDK\fR\m[]\&\s-2\u[1]\d\s+2
documentation)\&.
.PP
The possible statistics can be seen in the example statistics file (doc/examples/statistics
in the bugle source distribution)\&. It is important to read the NVPerfSDK documentation to understand what the different types of statistics are, what they mean, and the limitations of the hardware interface\&.
.SH "OPTIONS"
.PP
\fBflush\fR
.RS 4
If set, a
\fBglFinish\fR(3)
will be issued immediately prior to sampling the counters\&. This guarantees that events will be accounted to the correct frame, but will cause pipeline stalls\&.
.RE
.SH "BUGS"
.PP
Because NVPerfSDK operates across OpenGL contexts, it will count events from outside the debugged application\&. In particular, using
\fBbugle-showstats\fR(7)
to view the results will alter the statistics\&.
